Title: Improvements in or relating to lateral control means for aeroplanes
IPC: B64C9/28
Filed: 1938-12-17
Abstract: 525,401. Controlling aeroplanes. ROSE, W. K. Dec. 17, 1938, No. 36837. Convention date, May 21. [Class 4] Lateral control means for an aeroplane comprises wing tips each comprising a nosepiece, a fixed body portion and an aileron, the rear of the nosepiece and the front of the body portion being provided with curved vanes or blades forming a closable forward passage through the wing tip, and similar provision being made between the body portion and the aileron, the ailerons being tiltable about transverse axes to different angles in opposite directions, the parts being so arranged that on the side with the lowered aileron the forward and rear passageways can open under wind pressure to form passages of gradually diminishing cross-section from inlet to outlet with no straight line flow and on the side with the mixed aileron the forward passage is opened wide and the rear passage kept closed. The lateral control means comprising nosepiece 35, fixed body portion 36, aileron 37 and slots 38, 39 are constructed and arranged in the manner described in Specification 525,400, the slots having the general form described in Specification 497,500. The slot 38 is closed normally by a member 42 hinged to the nosepiece and including a curved part 50 which slides over a correspondingly curved part of the nosepiece. The slot 39 is closed normally by a member 44 hinged to the body portion and provided with a curved part 60 which slides over a curved part 61 of the body portion. The aileron central shaft 64 carries an arm 85 provided with a pin 86 which engages, a slot 83 carried by an axially-slidable rod 75. A spring 96 is interposed between an abutment 100 and a curved washer 99 and urges the member 42 to closed position. A further spring 116 engages an arm 106 to bias the member 44 toward its closed position. The aileron shafts are operated to move the ailerons differentially through different angles by means of levers 68, 681, Fig. 8, on the shafts connected by links 69, 69<1> to the arms of a bell-crank lever 70 mounted on a shaft 71 rotatable by a hand-lever 73. The parts are arranged such that on movement of the lever 73 to the right, the aileron 37 is lowered and the consequent pressure difference moves the members 42, 44 to open the slots. The degree of opening of the slots is, however, limited due to the movement of the pin 86 in the slot 83 and the action of the springs 96, 116. Simultaneously the aileron 37<1> is raised, the member 42<1> being moved by the rod 75<1> to wide open position whilst the member 441 is maintained in its closed position.

Title: Improvements in or relating to jig dyeing or like fabric treating processes
IPC: D06B3/32
Filed: 1934-12-31
Abstract: <PICT:0438834/IV/1> In order to prevent uneven straining or dyeing of a roll of fabric which has been subjected to a liquid treatment by running it from one roll to another to and fro through a bath of the liquor, by drainage to one part of the roll, it is continually oscillated bodily about its axis to hold the liquid evenly distributed.  As described, applied to a jig-dyeing machine, a roll of liquid-treated fabric during the time a sample of the material is being tested for colour is oscillated about its axis by means which may be brought into operative engagement with any one of a plurality of fabric roll-supporting means.  The machine may have a pair of shafts 18, 19 each supporting a beam 21 between which the material to be treated is passed repeatedly through a dye vat 14. A gear 48 carried on an arm 46 pivoted on the machine frame may be moved into engagement with gears 49, 51 on the shafts 18, 19 respectively, or to an intermediate neutral position, the arm being held in any desired position by engagement of a spring catch 57 operated by a handgrip 53 in one of a series of notches 59, 61, 62 on a sector plate 63 secured to the machine framing. The gear 48 is adapted to be oscillated through a clutch on the main shaft 36 of the machine controlled by a rod 43.  The gear 48 is oscillated by a pitman 66 connected to a crank 68 on the shaft 36.  The angle of oscillation of the rolls or beams 21 may be varied by changing the ratio between the gears 48 and 49, 51, and may, if desired, be several complete revolutions.

Title: Ac-dc converter
IPC: G01R19/22
Filed: 1965-09-01
Abstract: 1,113,904. Transistor amplifier and detector circuits. UNITED SYSTEMS CORPORATION. 1 Sept., 1965 [16 Nov., 1964], No. 37381/65. Heading H3T. [Also in Divisions G1 and G3] An arrangement for converting an unknown A.C. to be measured to an equivalent D.C. incorporates an input attenuator 2, the output from which is applied to a high gain transistor amplifier 14 whose A.C. output has positive and negative amplitudes which differ by an amount proportional to the unknown A.C. Negative current feedback is applied to the amplifier input via a loop 6. A filter arrangement 16 converts the amplifier output to the required D.C. In the circuit for the arrangement (Fig. 2, not shown) the input A.C. is passed via an attenuating network selected by a switch (36) according as to whether a measuring range of 1, 10, 100, 1000 v. or D.C. is required. The networks incorporate capacitors to provide frequency compensation at high frequencies. The attenuated signal at 3 is applied via an input resistor 4 and capacitor 80 to the first of three common emitter amplifier stages (82, 92, 104). Interconnection between stages is via diodes and the transistors operate a little above saturation. The output from the amplifier is taken from an emitter follower (112) and returned as a D.C. feedback to the amplifier input via a path including a Zener diode (178). This D.C. feedback stabilizes the operating conditions of the amplifier and standardizes the operating point of the amplifier output. The output is also fed to an A.C. feedback network 12 which is arranged by means of diodes (150, 152) and resistors (153, 154) to produce a voltage across a resistor (155) proportional to the amplifier output voltage, and this is supplied as current feedback to the input of the amplifier. The arrangement, wherein the A.C. to D.C. conversion takes place within the feedback loop, ensures that the amplifier gain and the rectifying element characteristics have negligible effect on the A.C.-D.C. conversion gain. The output from the system at the point 11 passes via a filter 16 to provide the required D.C. Details of the regulated supplies are given (see Division G3).

Filed: 1957-12-02
Abstract: 837,968. Electrically heated glass. LIBBEY-OWENS-FORD GLASS CO. Dec. 2, 1957 [Dec. 17, 1956], No. 37423/57. Drawings to Specification. Class 39(3) [Also in Group XXIII] Electrically conducting bent glass units wherein the bending takes place in a confined or normally reducing atmosphere are made by providing a sheet of glass with an electrically conducting film, applying a pair of spaced strips of fusible electrode material over the electrically conducting film, placing a second sheet of glass over the electrically conducting film and the electrodes with a parting material disposed therebetween, providing means between said sheets preventing the reduction of the electrodes, positioning the glass sheets on a bending mould and heating the glass sheets to fire the electrode material on to said first sheet and simultaneously bend said sheets; the conducting film may comprise tin oxide formed from stannic tetrachloride. The first sheet after filming is provided according to the known outline of the pattern to be cut from the sheet with electrode strips of a fusible material such as a metal flux. This flux should either contain a material to prevent reduction during pyrolysis or a substance providing oxygen should be applied close to the frit. A suitable flux comprises nitrocellulose, fine glass powder, silver oxide and silver powder. Alternatively, the inner surfaces of the glass sheets may be coated with compounds such as chromates, chlorates or peroxides which will liberate oxygen upon thermal decomposition. A suspension of potassium dichromate in methyl alcohol may be sprayed on to the sheets, and this will also form a parting material. After allowing the electrode material to air dry, a parting material such as sodium sulphate in methyl alcohol is applied over the electrode material and the glass sheet, and a second sheet placed thereupon. The matched pair are then positioned on a bending mould and passed through a tunnel furnace. The heating causes the glass to sink by gravity into the contours of the bending mould and at the same time the electrodes are fired on to the first sheet. It is desirable to apply extra parting material adjacent the electrodes to prevent them from firing on to both sheets. The bent sheets may then be pattern cut, lead wires may be soldered on to the electrodes and the sheets cleaned and finally laminated with a plastic interlayer such as polyvinyl butyral. Similarly, there may be made a curved electroluminescent panel in which a curved pair of electrically conducting glass sheets are used with a field-responsive phosphor and a dielectric material disposed therebetween.
